This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application Serial No. 60/293,949, filed on May 25, 2001, the disclosure of which is hereby incorporated by reference herein.
The present disclosure relates to architectural systems, such as headwalls, columns, and ceiling-suspended arm assemblies used in hospitals, and particularly to an architectural system adaptable to patient acuity level. More particularly, the present disclosure relates to an architectural system that is configured to deliver services, such as medical gases, to a patient and/or that is configured to support patient-care devices for delivering intensive care services to a patient.
Architectural systems, such as headwalls, columns, and ceiling-suspended arm assemblies, through which medical gases are accessible via medical service outlets are known. Headwalls, columns, and arm assemblies having rails, tracks, or brackets for attachment of patient-care devices and having electrical outlets for delivering power to the patient-care devices are also known. Patients in critical condition are oftentimes located in an intensive care unit of a hospital, whereas patients in stable condition are oftentimes located in a standard patient room. Architectural systems in intensive care units are generally configured to hold more patient-care devices and provide more types of medical services than architectural systems found in a standard patient room.
The numbers of patients in critical condition and the numbers of patients in stable condition fluctuate in a hospital over time. Thus, at any given time there may be either a shortage or excess of spaces for patients in an intensive care unit. In addition, at any given time there may be either a shortage or surplus of standard hospital rooms. Thus, there is a need for an architectural system that is adaptable to patients having high, medium, and low acuity levels so that hospitals have the flexibility to meet the needs of the patient population at any give time.
According to this disclosure, an architectural system adaptable to an acuity level of a patient supported by a hospital bed in a patient room having a wall and a ceiling is provided. The architectural system comprises a wall unit coupled to the wall and having a cavity, a ceiling unit coupled to the ceiling, and a column coupled to the ceiling unit for movement between a first position in which at least a majority of the Column is situated in the cavity and a second position in which the column is situated outside the cavity.
Various patient-care devices and equipment are attachable to the column. Such patient care devices include, for example, IV racks, infusion pumps, ventilation equipment, heart rate monitoring equipment, and patient data acquisition equipment. In an illustrative embodiment, a number of medical service outlets, Such as gas outlets and electrical outlets, are Coupled to the column. Also in the illustrative embodiment, a number of doors are Coupled to the wall unit for opening and closing the cavity. Thus, when the column is in the cavity, the doors may be moved to closed positions shielding the column and the equipment carried by the column from view and blocking access to the medical service outlets on the Column. Opening the doors, but leaving the column in the cavity of the headwall unit, permits access to some of the medical service outlets and to some portions of the equipment carried by the column. When the column is moved out of the cavity, all of the medical service outlets and all pertinent portions of the equipment carried by the column are accessible.
Also according to this disclosure, a ceiling unit having one or more pieces of equipment coupled thereto is provided. Such equipment includes, for example, a reading light, an examination light, a display screen, air curtain generation equipment, a privacy curtain, a temperature sensor, an air quality sensor, an air purifier, aroma therapy equipment, a motion sensor, and a proximity sensor. In one illustrative embodiment, an arm assembly is coupled to the ceiling unit and Supports an overbed table. The arm assembly permits the overbed table to be moved from one side of a hospital bed to an opposite side of the hospital bed.
A mobile cart is also disclosed herein. In an illustrative embodiment, the mobile cart comprises an upstanding pedestal, a plurality of legs coupled to a bottom of the upstanding pedestal, and a plurality of wheels. Each wheel is coupled to a respective leg of the plurality of legs. The legs, along with the wheels coupled thereto, are each movable between a first position extending outwardly from beneath the upstanding pedestal and a second position tucked beneath the upstanding pedestal. The mobile cart is attachable to a ceiling-mounted column or an arm assembly. The mobile cart is also attachable to a hospital bed to be transported with the bed. When the mobile cart is attached to either the Column, the arm assembly, or the bed, the wheels of the mobile cart are spaced apart for the floor. A headwall unit having a cavity configured to receive the mobile cart is also disclosed. The mobile cart carries one or more pieces of patient-care equipment Such as, for example, an IV pole, an infusion pump, a ventilator control unit, a gas tank, a gas control unit, a vital signs monitor, an on-board computer, a receiver, a transmitter, and a battery.
Further according to this disclosure, a set of hospital equipment comprises a headwall, a blanket, a unit housed in the headwall, and a hose coupled to the blanket and coupled to the unit, a thermoregulation medium being moved between the blanket and the unit through the hose. The thermoregulation medium includes, for example, heated air, cooled air, a heated liquid, or a cooled liquid. In some embodiments, in which the thermoregulation medium is heated or cooled air, the blanket has a plurality of perforations through which the heated or cooled air is expelled.

Headwall unit 232 has additional medical service outlets 216 mounted on a pair of lower vertical panels 218 which are situated beneath the lowermost pair of doors 58 as shown in
Another of the differences between system 230 and system 30 is that ceiling unit 238 of system 230 has tracks 198 which are wider than tracks 98 of system 30. Thus, tracks 198 extend laterally outward from canopy 96 of ceiling unit 238 by a greater amount than tracks 98 extend laterally outward from canopy 96 of ceiling unit 38. Each of tracks 198 have a cosmetic cover or panel 210. Each panel 210 has a first elongated slot 212 and a second elongated slot 214. In the illustrative embodiment, slots 212 are parallel with slots 214. Each slot 212 receives a respective side portion 132 of the associated carriage 88, 90 of the respective column 40, 42. Thus, provision of slots 212 in covers 210 allows columns 40, 42 of system 230 to move without interference from panels 210 between the respective storage positions within cavities 34, 36 and the various positions outside of cavities 34, 36.
In some embodiments, slots 214 are situated beneath respective track members (not shown) that are configured to support auxiliary equipment which is moved out of auxiliary cavities 234, 236 and, in other embodiments, auxiliary equipment is situated above slots 214. In the example shown in

A controller (not shown) housed in ceiling unit 338 or headwall unit 232 or both operates to control air curtain generator 272, the heating equipment (if any), and the humidification equipment (if any). A user interface is provided on one or both of columns 40, 42 or on headwall unit 232. A user inputs operational parameters, such as, for example, fan speed (high, medium, low), air temperature, and air humidity, to the controller via the user interface. In addition, system 330 has various sensors, such as, for example, a fan speed sensor, a temperature sensor, and a humidity sensor that provides feedback to the controller so that appropriate commands from the controller can be provided to air curtain generator 272, the heating system, and the humidification system to adjust the operation of these devices, if appropriate.
According to one aspect of the present disclosure, a patient rests on a hospital bed 534 in an environmentally-controlled hospital room 532 as shown in FIG. 17. Covering the patient is a disposable heating/cooling blanket 536. Blanket 536 is coupled via a pair of heating/cooling hoses 540 to a heating/cooling unit 538 housed in a headwall 542 of room 532. When the patient is to be cooled, unit 538 operates to provide a cooling medium, such as cool air or cool liquid, through one of hoses 540 to blanket 536 and the other of hoses 540 provides the cooling medium back to unit 538 after circulation of the cooling medium through blanket 536. When the patient is to be heated, unit 538 operates to provide a heating medium, such as heated air or heated liquid, through one of hoses 540 to blanket 536 and the other of hoses 540 provides the cooling medium back to unit 538 after circulation of the heating medium through blanket 536. In those embodiments having heated air or cooled air circulated through blanket 536, perforations are formed in the surface of blanket 536 facing the patient so that a portion of the heated or cooled air being circulated through blanket 536 is able to escape from blanket 536 through the perforations and convectively heat or cool, as the case may be, the patient.
Bed 534 includes a pendant controller 544 that a patient uses to control heating/cooling unit 538 in a desired manner when pendant controller 544 is not locked out. In some embodiments, pendant controller 544 also is used to control other bed functions, such as articulation, raising, and lowering of the bed deck, and to control room entertainment and communication functions, such as television, radio, and nurse call. Bed 534 includes a footboard 546 having a control panel 548 that is used by a caregiver to control operation of unit 538, to control operation of various bed functions, and to control various entertainment and communication functions. Control panel 548 is also used by the caregiver to lock out one or more functions of pendant controller 544. For example, the caregiver can lock out the ability of pendant controller 544 to operate unit 538.
An ceiling unit or overhead canopy 550 is coupled to a ceiling 552 of hospital room 532 above bed 534 as shown in FIG. 17. Canopy 550 includes various systems that control the environment of room 532. For example, canopy 532 includes an overhead temperature sensor (not shown), an overhead air quality sensor (not shown), an overhead air purifier (not shown), aroma therapy equipment (not shown), motion or proximity sensors 554 for detecting the presence of other people in the hospital room, examination lights 556, reading lights (not shown), and a video screen 558 for displaying one or more preselected images. Such images may include a scene from nature or other restful scenes. Such images may also include images that transition at the appropriate times during a 24-hour period from day images, such as clouds and Sun, to night images, such as moon and stars. Images of the patients family may also be displayed on screen 558.
In some embodiments of room 532, the room lights are controlled to dim slowly as the daytime turns to evening. In addition, a recording of evening sounds, such as owls, night birds, crickets, and wind in the trees is played by audio equipment housed in overhead canopy 550. Eventually, the room lights are turned completely off and the night sounds fade away. In other embodiments of room 532, a video screen similar to or larger than video screen 558 is mounted to a room wall, preferably a wall that confronts the foot end of bed 534. In such alternative hospital rooms, television images, internet images, educational information, patient schedule, imagery to promote relaxation, and video conferencing images are selectively displayed on the video screen.
Bed 534, unit 538, and ceiling unit 550 each have their own controllers for monitoring and controlling the various functions associated with these devices. Each of such controllers include, for example, one or more microprocessors, microcontrollers, memory circuitry, input/output circuitry, signal conditioning circuitry, signal conversion circuitry, power conditioning circuitry, and the like. It is within the scope of this disclosure for each of the controllers of bed 534, unit 538, and canopy 550 to be coupled to the hospital computer network to exchange data with the network. In some embodiments, parameters for controlling bed 534, unit 538, and canopy 550 are entered by computers that are located remotely from room 532. Thus, for example, if a patient places a nurse call requesting the heating/cooling function of unit 538 and blanket 536 be adjusted or discontinued, the nurse receiving the call is able to adjust the amount of heating/cooling provided to the patient via blanket 536.
